Congratulations to Matt Wersebe!

Congratulations go out to Matt Wersebe for being awarded grant support from the OU Graduate Student Senate (GSS) and the OU Graduate College Robberson Grants Program to help fund his on-going doctoral work.  Matt has been examining the impacts of man-induced salinization (i.e., road salt input) of freshwaters systems in the Twin Cities of MN on the population genetics/genomics of our favorite model organism, Daphnia.  This funding will help Matt proceed with DNA extraction and DNA sequencing this coming year.  Great job, Matt!

To a job well-done! Congratulations, Ekene!

Yesterday, Ms. Ekene V. Nwakoby  successfully defended her Honors Thesis, entitled, “Differences in Physiological Responses and Life History Characteristics between Ancient, Modern and Hybrid Daphnia pulicaria Genotypes in Response to Variation in Food Quality and Quantity”.  Congratulations, Ekene, for doing a great job!


A successful OU BIO EXPO yesterday!

Our lab group was one of many Biology Department labs that participated in the 1st annual OU BIO EXPO held in the Beaird Lounge of the Oklahoma Memorial Union.   We want to thank the dedicated staff of the Dept. of Biology for organizing such a great outreach event!

2019 ESA Simberloff Award to Emily Kiehnau!



We want to share some exciting news from Emily Kiehnau. She just received word that she is the recipient of the Ecological Society of America (ESA) Invasion Section’s 2019 Simberloff Award for Outstanding Student Presentation (oral presentation) at the 2019 meeting, which was held last month in Louisville. She presented results from her 2nd Chapter of her dissertation (entitled “Morphological changes of native Daphnia species in response to the invasive predator Bythotrephes longimanus“).  Please join us in congratulating Emily on a job well done!

Welcome to all the new members of the lab!

We would like to welcome our new lab members, Juliet Agadagba, Kaylee Gibbons, and Amber Woolley, who will all be conducting Independent Research in our lab, this academic year!
